Question and Answers


I have a lifestyler 8.0 treadmill model number 831297402. The console has LED read outs for time, speed, calories and distance. Those readings are stuck on 0.


The problem might be in the console, the reed switch (speed sensor), reed switch wire, or the magnet mounted in the pulley on the front roller.

The pulley on the front roller has a small magnet inserted in it. The speed sensor is a small reed switch that mounts withing 1/4 inch of the front roller pulley. The reed switch might have gotten out of position.

To test the reed switch, disconnect the power to the treadmill and remove the motor hood. Disconnect the reed switch wire from the console and connect the probes from an ohm meter to the 2 wires. Rotate the front roller until the magnet is near the reed switch. The meter should read 0-2 ohms. Rotate the pulley so the magnet is not near the reed switch and the ohm meter should read open circuit or infinity.

If the reed switch is sending the correct signal to the console, the console is bad.

Most times this problem is a reed switch out of position.
